TYPEWRITING MACHINE.

Appueation'nled November 29, 1922. serial No. 603,910.

T all whom t may concern.

Be it known that I, GEORGE A. SEIB, citizen 'of the United States, andresident of Ilion, in the county of Herkimer and State of New York, have.invented certain new and vuseful Improvements in Typewriting Machines,of which the following is a specification.

My invention'relates to noise reducing devices for typewriting machines,and its general object is to provide new and improved devices of thecharacter specified. One of the specific objects of the invention is toprovide a noise reducing or sound deadening frame for a typewritingmachine; an-

other object is to provide closures, plates or panels having sounddeadening characteristics to a marked degree; and another object is toprovide an improved type bar rest which minimizes 'the noise due to theirnpact of the type bars on their returnafter printing and is moreoverso related to other parts-of the machine as to assist in providing asubstantially enclosed space to accommodate the actuating. mechanism forthe type bars. Other objects will hereinafter appear. i l

To the above ends my present invention consists in the features' ofconstruction, combinations of devices and arrangements of parts,hereinafter described and particularly pointed out in the claims.

My invention is illustrated in the accompanying drawings, wherein i 5Figure 1 isa fragmentary front to rear vertical sectional'view of a No.l2 Remington typewriting machine embodying the invention.

' Figure' is a fragmentary sectional view taken on the plane indicatedby the section lin 4 4 of Fig. 2 and looking downward, an

Figure 7 is a fragmentary plan view showing the central part of thebottom plate.

As appearsfrom Figs. 1 and 2, the main frame of themachine comprises arectangular base composed of sides 1, a rear part 2 and a front partwhich is omitted from the drawing. Rigid with the base and rising fromit are posts 3 angular in cross section, and to the top of said posts issecured a top plate 4 finished at its edges with the usual downwardlyextending lip 4a. The machine is supported o n rubber feet `5 which aresecured to the main frame by screws 6 (Fig. 3). Rigid with the mainframe is a type bar support or segment 7 which is vertically disposedand is formed with radial guide slots indicated at 8 in which aredisposed the type bars 9, said type bars being pivoted on a commonfulcrum wire 10 mounted on the segment 7. The set of type bars isarranged in an arc of a, circle, the bars being normally horizontallydisposed and each provided at its front end with an upper case and alower case type. At its rear portion each type bar is formed with a camslot 11 which is engaged by an actuating pin 12 projecting laterallyfrom the upper end of a lever 13. This lever is only fragmentarily shownherein but is one of the. elements of the key o erated actuatingmechanism of the type ar which is of known construction, being found inthe No. 12 and also the No. 10 Remington typewriting machine, saidmechanism com rising an actuating train which extends low the type barand connects it with its key lever,

which is horizontally disposed and arranged within the base ofthemachine, all as is well understood. At their forward ends the key leversare guided in slots formed in the downwardly extending portion of av^sheet metal comb plate 14 which is secured by screws 15 to4 acrossbarl 16 rigid with the base. Below and somewhat forward of thepivot 10 each type bar is curved or necked along its under ed e asindicated at 9a, the curve projecting ,j `ownward and merglng into thestraight under edge of the bar. Normally the type b ars rest on a thickarcuate pad or cushion 17 which may be of felt or other sound deadeningmaterial, this pad being unusually wide! and underlying the ioo straightportion of the bars from near their type ends to and partly under thecurved under edges 9a, the rear upper edge portion ofthe pad 17 beingground to provlde a curved or roundedl corner 18 which conformssubstantially to the front parts of the curved, convex or hump portions9 of the type bar. rll`his enables the pad 17 to be extended from nearthe type ends of the bars rearward comparatively close to they pivots ofthe bars and so that the bars may as they return kcontact or engage withthe pad` at their curved portions close to the pivot 10 withoutobstructing or .interfering withkthe return movements. By bringing thepoint. of contact of the type bars close to theirfulcrum the noise dueto impact may be somewhatreduced: Moreover, by reason of providing awide or broad cushion or pad, the felt or other material of which it iscomposed need not be so hard or compressed to the same-degree as when anarrow, ad is employed. inthe present instance t e pad or cushion 17 ispreferably of such consistency as to permit the type bars, after themachine has been in use some time, so to compress thel pad as to contactwith italong its full width- The pad 17 is secured in any suitable Wayas by shellac to the upper face of a wide arcuate basket 19 whichprefer-y ably is a casting of aluminum or other light metal, and isformed along its upper face with a rib or projection 2() against whichthe front edge of the'pad 17y may abut. rllhe basket or casting 19 isillustrated in Figs. 1 and L5. At the middle of its under side thecasting is provided with a downwardly'extending lug 21-and it'terminatesat its ends in horizontal? flanges 22. Forward of the flanges are lugsor enlargements 23 which project beyond the front edge of the castingproper and have finished front faces. The top of each end flange 22 isformed A.with a large boss 24 and a-smaller boss 25, the top faces ofwhich are machined or ground in order that they may contact closely withthe under edge 01E a rib or downward projection 26 formed integral withthe top plate 4 and extending rearward along and under said top plate,finally merging in the usual trough or'depression 27 with which the ktopplate is provided. Said top plat'e generally correspondswith thatvof theNo. 10 Remington machine, except for the extended rib 26. At its frontsaid rib terminates in a circular enlargement corresponding with theunder- 'lying boss 24. Headed screws 28 pass downward through the topplate and said circular enlargements and are threaded into the bosses24, thus securing the castin or basket 19 to the main frame of the macine. The screws Y 28 `maintain the bossesV 25 tightly against the ribs26 ,and thus promote the rigidity of the wide ty e bar rest, compris-vAf ing the basket 19 and t e pad or cushion 17,

imanes 'deaden or reduce .the sounds of the operating or working partswithin it, the closures or coverings comprising plates or panels appliedto the front, rear, sides and bottom of the frame. As appears :tromFigs. 1 and 5, the front plate or panel 29, which like all the others ispreferably made of sheet metal, is generally rectangular in shape and isprovided with a central circular cutout corresponding with the curvatureof the type bar system. The plate 29 is formed with a flange orrearwardl bent portion 30, which provides the boun ary of thiscutout,said flange as will be understood from Fig. 1 being substantiallyin line with the types as they lie in the basket. At its bottom andsides the plate 29 is formed with bevels or inclines 31 terminating instraight portions v 32 which lie close to the front flanges of the frontcorner posts. At its left the iront plate is provided with a cutoutindicated at 33 to accommodate parts of .the ribbon changing mechanism.'llhe front plate 29 is mounted on the type bar rest, being secured tothe casting 19 by three headed screws 341. 'lwo of these screws arethreaded into the `front faces of the lugs 23 and the third screw isthreaded into the lug 21. Secured to the rear face of the plate 29 is asound deadening\pad 35 of Jfelt or the like, said pad being shaped ingeneral conformity with the shape of the plate 29 but not eX- tendinfurther than the bevel portion 31 thereo rlhe beveled plate 29 presentsa finished appearance from the front of the machineand co-operates withthe comb plate 14C substantially to close the front of the machine belowand at the sides of the type bars as they lie in the basket. The flange30 overlaps the top edge of the pad so that it is not visible from thefront.

rll`he closurev plates employed to cover the sides of the' machine areeach designated asa whole by the numeral 36 and are illustrated in Figs.1 and 2. Each of these plates extends from one of the front corner posts3 to the companion rear corner post 3 and from the top of the machineunder the top plate @substantially to the lower edge of the'side 1 ofthe base. The top edge oi each plate 36 is cut out or shaped to corre-Spond generally with the outline of the top plate, said top edge beingclear oi the top Inl llo

*Y bein secured to the-.inner faces respectively of the plate'parts 59,60. The inner ends of -these pads of course terminate short of theinterlock which secures the two plates together. v

The bottom plate, panel or closure indicated as a whole by the numeral70 is illustrated in Figs. 1-4 and 7. Thisgplate or panel 70 isgenerally rectangular in shape,

cutout at its front corners as indi- A' cate at 71 and near its rear asindicated at 72 to clear the feet, of which it is independent. The'panel generally is Ilat with a central depression and bent side edges.The

rear part 73 of the panel, behind and in line with the rear feet 5, isfiat and horizontal. Forward of this rear part, the panel is loweredsothat the main body of the bottom portion llying between the four feet 5is depressed or dished so* that its bottom 74 is considerably lower than-the rear portion 73, as well as the flat'horizontal front portion 7 5and the side portions. It will thus be seen that from the bottom 74 thep an or plate slopes upwardv at the `iront, back and sides,providing'incline'd portions 76. At the front and back respectively theinclined portions connect with the flat portions 75 andl 73, while atthe sides the inclines i l76 connect with narrow flat horizontalportions 76 which are in the plane of the portions 75 and 73. The outeredges of the flat portions 76a are bent upward providing short inclines7 6b, which terminate just inls)ide the verticalV planes of the sides ofthe ase. l

Centrally the bottom portion 74 is slit or cut out to provide angularlydisposed or diverging slotways 77, the slotways having a common centerand providing separate portions or tongues 78 which diverge from acommon center, which substantially is the center of the plate 70^itself.The slotways 77 extend outward towardsthe corners' of the main body ofthe plate andin eEect divide orseparate it into several parts. Bridgingthe slots and connecting the tongues or parts 78 is a tie-piece or disk79, this tie-piece being detachably secured to the under face of thebottom art 74. The tie-piece or disk is referably ormed of metal of adifferent thickness from the metal of the bottom plate 70, the disk 79in the present `instance being thinner than the bottom plate. Thedislemay be attached to the bottom plate in any suitable manner. Atongue and slot connection is shown herein, the disk 79 being formedwith diametrically opposite tongues or projections 80, therebeing Afourof such tongues in the present instance, these tongues 80 passingthrough slots indicated at 81 near the points of the tongues 78, thetongues or projections 80 then being bent inward on themselves so as tosecure the disk 79 in lace. ln the present instance the disk is tightlyheld against the bottom of the part 74.A It has been found in effectthat by employing the closure plate in combination with a part securedto it, the ringing noise incidentto prior plates has been minimized;also the slotting of the plate to provide a number of parts or tonguesand thus interrupting the vibrations of the metal sheet as a whole,minimizes the drumming noise incident to the use of plates of otherconstructions. A rectangular sound deadening pad 82 is secured to theinner face of .the part 74, said pad having side tabs or extensions82,LL which overlie the rear portionsof the sides of the bottom plate.Another pad l83 is secured to vthe top of rear part 73 of the plate,this pad beingrformed vwith recesses indicated at 84 to accommodate theunder face of the base of the machine by headed screws 86, there beingfour such.

screws, two atithe front and two at the rear. l I.

The two rear screws are 4threaded into vthe ino .pads 82, 83 and 85 isdetachably secured to j bottoms of lugs 2v integral. with the rearv part2 of the base. These screws are shouldered, the shoulder portionspassing through smooth holes in the part 73 and padv 83 and theshoulders abutting' against the bottom of the lug 2B.' Interposedbetweenthe heads of the screws 86 and the bottom face of the plate part-.74' are washers 87 and 88, the outer washer 87 beingof metal and theinnerwasher 88 of felt.' At the front side, the two secury ing screws 86arelikewise shouldered, the

shouldered portions passing upward throughl smooth holes in the platepart 75 and the pad 85, theushoulder kof each screw abutting against arectangular reinforcing strip 89y art 90 of which is' securedtothe'bottom the trough-like'portion 91 of a s eet metal member which ispart of the regu-lar equip.

`and are threaded into the posts 3.

uniones top plate so as to' presenta finished appearance to the eye. Theside edges of the plate 36 are straight and overlap slightly the posts 3to which the plate is secured near its top b v headed screws 37 whichpass through slots indicated at 38 in the plae 'l e lower portion ofeach plate 36 is detachably secured to the side 1 of the base by.

headed screws 39. Each plate 36 is formed with a bevel 40 extendingaround its sides and lower portion, the. bevel giving an outwardlyprojecting panel effect to that portion of the plate which is within itand thus adding to the appearance. At its rear portion the inner face ofeach plate 36 has suitably secured to it a sound deadening pad 41 offelt or the like. f

The forward portion of ,each plate 36 is provided with a door to giveaccess to certain of the working parts including ribbon mechanismcontained within the enclosed .part of the machine. The ribbon mechanismcomprises ribbon spools 42 vertically arranged below the top plate, oneat each side ofthe machine and towards the front thereof.' 'lhe spools42 are so disposed that they project outward somewhat bevond the -foreand aft plane of the side plates 36.v

The doors 43 are arranged in cutouts indi- 'cated at 44 in the sideplates, these cutouts being opposite the ribbon spools-42 and exposingthem to view from the sides ot themachine.

The cutouts are'rectangular in shape and the doors 43 which when closedcompletely cover the cutouts are of course correspondingly shaped. 'llhedoors 43 are hinged or pivoted along their bottom edges. Each hingecomprises a long pivot pln or rod 45 horizontally disposed at the lowerside of the cutout 44 and its middle portion is supported by a tongue 46projecting upward from the lower edge of the cutout and curled on itselfto provide a tube-like bearing 47 for the pivot pin. 'llhe lower ends ofthel door 43 are correspondingly curled to provide tube-like portions 48through which the outer ends of the pin 45 pass,

l said'outer ends thereby vsupporting the door.

slightly to retain the pin 45'in'place.

@ne of the tubes 48 may be punched gn t will be understood that the doormay be swung outward and downward about the hinge or pivot. 45completely to uncover the opening 44, this opening being of suflicientsize to enable the hand tobe introduced for the removal of the adjacentribbon spool or `other purpose. As has been stated the outer `portion ofeach ribbon spool projects becess or pocket 49. Opposite the spool thepocket 49 is curved outward in conformity with the curve of the ribbonspool and its sides 50 incline downward and merge into the flatface orplane of the door, giving a neat appearance.

Each door is held in place by a latch 51 provided with a beveled orinclined engaging outer end portion 52 (Figs. 1 and 1a). rlhe latch ispivoted to the inner face of the door near its forward side on a pivotpin 53, which 'bears in and projects through the door 43, the outer endof said pin being provided with a thumb piece 54. 'llhe inner end of thepin terminates in a head 55 and confined between the head 55 and thelatch 51 is a coiled spring 56 which presses the latch against the innerface of the door when it is opened. The construction permits the latchto yield inward lengthwise of the pin 53 when the door has been closedand the thumb piece is turned to rotate the latch. causing it to engagewith the inner face of the plate 36 forward of the door. During thisturning movement the bevel portion 52 of this latch exerts a caminingeffect. forcing the spring 56'to yield to permit the latch to passbehind the plate 36. The side of the pin 53 may be flattened asindicated at 57 and the hole'in the latch may be correspondinglyflattened so as to.

cause the latch always to turn with said pin while being adapted toyield lengthwise thereof. A ystop pin 58 projecting inward from theplate 36 limits turning movements of the latch in locking direction.

The rear plate, panel or closure is illustrated in Figs. 1. 2 and 6 andconsists of two parts 59 and 60, these parts being adapted to interlockat their inner faces, the interlock comprising an inwardly projectingtongue 61 on the part The inner end portion of the plate is providedwith a lip 62 which is bent back on itself, the lip'at the bent portionbeing cut to provide a slot indicated at 63 in which the tongue 61 isadapted to engage. This tongue is slightlyl off-set as shown in Fig. 6and when the parts 59 and 60 are connected, said tongue is confinedbetween the lip 62 and the inner portion of the plate 60, thus providinga tight interlock between the two parts` which however may be readilyseparated when the two-part plate 59. 6() is detached from the machine.'llfhe upper edges of each of the plates 59 and 60 are irregular inshape as shown in Fig. 2 to accommodate different working-parts ofthemachine. lt is not thought necessary to describe this feature indetail although it may be said that the main cutout indicated at 64 inthe plate 59 is to provide space for part of the springA drum mechanism,while the central irregular cutout, indicated at '65, partoi said cutoutbeing in the late 59 and part in the plate 60, accommo ates theescapepairs of washers 92 and93, the outer washer of each pair being ofmetal and the inner washer 93 of felt or other sound deadening material.The attaching means for the bottom plate as above described holds saidplate securely against the bottom of the machine which it completelycovers rearl ward of the front posts.

Various changes may be made without departing from my invention.
